Config 
The config object represents global settings for the SDK. It exposes properties to define global values used by the SDK, such as the API key, map units, and languages.
Example
import * as maptilersdk from '@maptiler/sdk';
maptilersdk.config.apiKey = "YOUR_MAPTILER_API_KEY_HERE";
maptilersdk.config.primaryLanguage = maptilersdk.Language.FRENCH;
